Unread Topic URL Link Not Working On MCP View Forum Topic List

If a topic has a new post, you can usually click the red topic image and it will take you to the first new post.

On the MCP View Forum page, if you click the image, it loads the same page again because the URL is empty.

Affected Code:

<!-- IF topicrow.S_UNREAD_TOPIC --><a href="{topicrow.U_NEWEST_POST}" class="row-item-link"></a><!-- ENDIF -->

Cause:
This code does not work on that template:

{topicrow.U_NEWEST_POST}
